STM32CubeProgrammer USB DFU not detected on linux

[VNong]

Hi,

USB DFU did not work in STM32CubeProgrammer in Linux. The programm did not detect the usb port. But it works faultless in STM32CubeProgrammer in windows.

I tested with STM32CubeProgrammer V2.10 and 2.12, same results.

I have linux mint 20.3 Luna

Can it be a permission problem? Do you have udev rules to give access to non-root apps?

same on my linux (MX18) ; stlink working fine; dfu mode seems not "known device" to system,

dmesg shows:

so cannot enumerate.

in Win you need load a special driver for "STM in dfu mode" , otherwise you get same "unknown device" message I had this on my Win7 pc ! ) ; newer installations of stm ide or Cube do it auto and install this driver. (or maybe Win10.. has it in its list to install if needed.)

[Pavel A.]

This is not same. If the device is recognized at all, this isn't a setup or enumeration error.

Yes it causes permission. It worked when I ran program with sudo. I will try to set the udev rule.

Thanks!
